Answer:
Isn't this like having enough energy to supply the world for centuries with just 1% of the sea's force?
Explanation:
I guess it's because the amount of energy in it can supply energy.
Is this all you need or more ?
Answer is "A".
Explanation;
Physical changes mean an arrangement of particles of a given substance without producing new substance but changes in physical form of the substance.
<em>Example :</em> vaporization of water ( water goes its gaseous phase from liquid form).
Chemical changes mean an arrangement of particles while forming new substance.
<em>Example : </em>heating of CaCO₃. (In this process CaO and CO₂ are formed).
In this problem, the volume of water has decreased. Hence, it can be said that this is an example of physical changes due to not forming of new substance.
